Application filed February 8, 1913. Serial No. 747,182.

To all whom it may concern:

automatic means for preventing the setting or introduction of numbers into the machine preliminary; to adding or recording operations at selected or predetermined intervals. I

Another object of the invention is to provide settable mechanism whereby the keys of the machine are locked or disabled, there- 'by preventing the setting or introduction of numbers into the machine, at selected or predetermined intervals atthe option of the operator.

Another object is to equip an adding and recording machine with mechanism for antomatically locking the keys of the machine to prevent operation of'thekeysat selected or predetermined intervals, thereby preventing the setting orintroduction of numbers into the machine until said key-locking mechanism has been released.

In commercial use it is frequently desirable to list the items in parallel columns upon a single sheet ofpaper, for instance,

and it is desirable that, eachof the several columns shall contain an equal number of ltems. For example it may be desirable thatv manufactured 1n substantial conformlty with protecting the operator from error by ren- 7 .dering it impossible up for the operator to set or introduce into the machine an excessive number of items for any of the several columns. i

For purposes ofconvenience I have illustra ted'the present embodiment of my invention in the Dalton adding machine, which is Hopkins Patent No. 1,039,130, dated September 24, 1912. The said Dalton machine, as it is now in commercial use and as de: scribed and illustrated in said Hopkins Patout No. 1,039,130, includes a series of numeral keysl arranged in suitable relation in a key-board and mounted upon levers 2, which extend toward the rear of the maohine, and which are operable in the well understood manner to set up numbers. in a carriage 3, preliminary to the adding or listing of said numbers. The numbers which are set up or introduced into the carriage 3, by depression of the keys 1, are recorded by operation of the type-carriers 4, and may be added by the adding wheels 5 through the movement of the racks 6 which cooperate with the type-carriers, the movement of the type-carriers and racks being determined by the parts in the carriage which represent the numbers set up or introduced into the carriage by operation of the numeral keys. It is well understood that the operation of the type-carriers and racks, for adding and list ing purposes, is controlled by the rocking of a shaft 7, which is rocked forwardly to permit forward movement of the racks and typecarriers and which is rocked rearwardly to restore the racks and type-car riers to their idle positions. The mechanism for effecting these operations may be of any preferred construction and arrangement, or the shaft 7 may be rocked in one direction'by a handle 8 and in the other direction by springs 9. 'It is necessary to move the racks and type-carriers forwardly and rearwardly for each item listed or added, so that the shaft 7 forwardly and backwardly for each item listed or added.

The paper is fed to the type-carriers around a platen 10 mountedin a laterally movable carriage 11 so that different columns of the paper may be presented to the type-carriers, thereby enabling the operator to list numbers in parallel columns on the same sheet of paper.

he mechanism above described is substantially the same as that contained in the Dalton machine and as described in detail in the Hopkins patent referred to. It being understood, then, that reciprocation of the type-carriers and racks is necessary for each item recorded or added, and that operation of the shaft 7 is also necessary for each item recorded or added, no further detailed description of the structure of the Dalton adding machine or of the structure of the machine of the Hopkins patent aforesaid appears necessary. It-is with these existing dwell understood portions of the Dalton machine and the machine of the Hopkins Patent N 0. 1,039,130, that I have illustrated my invention which will now be described.

A link 12 has its lower end pivoted to an arm 13 attached to the shaft 7 and its upper end having pin-and-slot connection 14 with the forwardly extending arm of a bell-crank lever 15, which is pivotally supported upon a shaft 16. The upwardly extending arm of the lever 15 carries a laterally extending portion 17 upon which is ating pawl 18. A spring 19 is arranged to actuate the upper arm of the bell-crank lever 15 rearwardly and a spring 20 connectit is also necessary to rock ing the rear end of the actuating pawl 18 with a stationary element, actuates the forward end of said pawl 18 into engagement with the ratch t wheel 21 upon which said pawl acts. 1 i

The ratchet wheel is attached to aopening in the case into which they extend.

The extent of rotation of the sleeve 22 is limited or defined by a projection 25 on the flange 23, and of the machine extending into the path of movement of the projection 25, and constituting an abutment to limit or define the extent of rotation of the sleeve 22. The normal or idle postion of the parts, when they are set to permit the maximum rotation of the sleeve 22, is that illustrated in Fig. 2, in which the projection 25 rests against the outer or right hand side of the. projection 26. A motor spring 27 mounted between the flange 23 and plate 24, within the opening in the case, actuates the sleeve 22 toward its idle position in which the projection 25 is against the outer or right-hand side of the projection 26, so that when the sleeve 22 is turned anti-clockwise, the spring is wound or tensioned.

Since the actuating pawl 18 is moved rearwardly on the forward rocking of the shaft 7 in any recording or adding operation of the machine, and is moved forwardly on the return movement of the shaft 7, the said pawl 18 will rotate the ratchet wheel 21 step by step. It is, as a result of this operation, that the keys are locked at any predetermined time, the locking mechanism being actuated directly as a result of the movement of the ratchet wheel 21.

A rod or spindle 28 is revolubly mounted in the sleeve'22. also longitudinally movable, and is provided on its upper end with a knob 29 which constitutes means for manual engagement as required for setting the key locking devices to lock the keys at the desired predetermined intervals. A spring 20 is interposed between the notch 29 and the upper extremity of the sleeve 22; thereby yieldingly supporting the rod or spindle in its normal and elevated position. To the lower end of the rod or spindle 28 an arm 31 is attached. The arm 31 supports a cam block 32, and two bores or recesses are formed within said cam block. Each of said bores or recesses retains a coil spring 33 which encircles the lower endsof the latch bolts or pins 34 whose upper ends extend into and a projection 26 on the-case- Said rod or spindle is.

. or spindle.

through holes in the arm 31. Ribs or flanges on said latch bolts or pins 34 rest upon the upper ends of the spring 33, so that said springs actuate said latch bolts or pins upwardly; said flanges also engage against the under side. of the arm 31 in order to limit upward movement of said bolts or pins. the same radial line from the center of the rod or spindle 28, one of said bolts or pins also being nearer than the other to said rod Two annular series of holes 36 are formed in the ratchet wheel-21, in this instance each series or annular row of holes include 53 holes. The holes 36 of one row or series are in staggered relation, that is on different radial lines in the ratchet wheel, with respect to the holes. 36 in the other annular row or series. The protruding ends of the pins or bolts 34 are adapted to engage in the holes 36 and thereby lock or latch the cam block 32 and the ratchet wheel 21 together. Because of the staggered relation of the holes 36 of one row or series with respect to the holes of the other row or series, and because there are 53 holes in each row or series, it is obvious that there are 106 possible adjustments of the cam block 32 with respect to the ratchet wheel 21.

A plate or disk 37 is attached to the top of the'case of the machine over the plate 24 and is provided with an annular scale or indicator upon its upper surface adapted, by cooperation with a pointer 38 keyed on the rod or spindle 28 above the end of the sleeve 22, to register or indicate the position of the cam block 32, thereby designating the number of items which may be added or recorded before the keys become locked. These devices enable the operator to adjust the locking mechanism precisely so that any desired number of items within the capacity of the mechanism may be added or recorded in each of the several columns.

As previously explained, each operation] of the shaft 7 effects a step movement of the ratchet wheel 21, and also of the cam block 32 which is in locked engagement with the ratchet wheel. After the predetermined number of step movements of the ratchet wheel and the cam block have occurred, the cam block engages or contacts with the upwardly extending end of the bell-crank lever 39. A lever 40 connects the opposite end arm of the bell-crank lever 39 with an arm 41 attached to a rock shaft 42, properly supported with respect to the key levers 2; The connection between the link 40 and the arm 41 is a pin-and-slotconnection 43, a spring 44 holding the arm 41 at the upper extremity of the slot. A plate 45.is supported by the base of the machine transversely of the key levers 2, and is provided with a series of notches or slots 46 within which the key leversoperatively extend. Locking plates The bolts or pins 34 are on 47 are pivotally supported by the plate between the notches 46, the lower ends of said plates being provided with shoulders 48 against which the key levers 2 engage when depressed. Therefore, when any key lever 2 is depressed it'engages the shoulder 48'of the locking plates at each side of said ally, and preventing the depression of any other key until the locking'plates are released. A slide plate 49 is supported by the plate 45, and is provided with an' arm or with the locking plate 47 at oneend of t series and thereby prevent movement of any of the locking plates and look all of the keys against operation. A spring 51 yieldingly holds the locking plate 49 in position so that the projection is out of contact with the locking plate 47, thereby normally permitprojection 50 adapted to be moved to engage e ting any of the keys to be depressed. An

, key lever, actuating the locking plates laterder 54 on the slide plate 49, thereby actuating or moving the slide plate 49 laterally;

and causing the projection 50 to engage against the locking plate 47 at the end of the series and thereby look all of the locking ates to prevent operation of any of the umeral keys.

From the foregoing description it will be seen that the operator may selectively set ,the locking devices so that the keys will be .locked at any predetermined time, or after any predetermined number of items have been added or listed, within the capacity of the item counting or indicating devices 37--38. It is also clear that the keys are automatically locked when the last item of the desired predetermined number of items is listed or added in any one of the several columns, or in a single column, as thecase may be. As previously mentioned," the carriage and platen 10 are laterally movable for the purpose of presenting different columns of thepaper to the recording mechanism. Any suitable, or known, carriage retaining or holding devices may be employed, such, for instance, as those illustrated and described in the Hopkinspatent aforesaid, but since the form of the carriage. retaining and holding devices constitute no part of the present invention such devices are not herein illustrated. It-is sufficient for the purpose of this application to understand that the carriage and platen remains laterally immovable until the desired number of items have been listed or added in each of the several columns, and after the desired number of items have beenlisted or added the carriage is moved laterally to present another column of the paper to the recording mechanism. The lateral movement of the carriage and platen involves the rocking of a rod or shaft 54 (Fig. 1), bymeans of a lever 55 or other suitable device. The rod 54 presents a flat surface against the upper end ofa lever 56 which is pivotally mounted upon a support 57 on a stationary member, so that when the rod 54. is rocked the lower end of the lever 56 is moved forwardly. The lower end of /the pro the lever 56 rests against the rear extremity of an actuating element 58 which is upheld by supports 59 attached to the case or some other part of the machine. The actuating element 58 is longitudinally movable on the supports 59.

At each stepping movement of the ratchet wheel 21 said wheel is engaged and retained by a retaining pawl 60 supported upon a stationary support 61 and actuated into engagement with the ratchet wheel 21 by a spring 62, connecting an arm of said pawl with the support on each pawl. The for-, ward end of the actuating element 58 presents a beveled or oblique surface against a projection on the pawl 60, so that forward movement of the actuating element 58 re leases the pawl 60 from the ratchet wheel 21. A projection 63 on the element 58 engages behind an arm on the actuating pawl 18, so that forward movement of the element'58, in addition to releasing the pawl 60, also releases the pawl 18 from the ratchet Wheel 21. the ratchet wheel 21 at each lateral movement or column spacing of the carriage and platen. When the two pawls are thus released the motor spring 24, (Fig. 1) restores the sleeve 22 and the ratchet wheel 21 to'idle osition in which the projection 25 (Fig. 2 is against the right hand side of ection 26. This adjustment permits the listing and adding of the same number of items as were listed or added in the previous column, and after an equal number of items have been listed or added in the newly positioned column, the keys are again automatically locked against operation as in the previous instance. When the carriage or platen is positioned to present a new column of the paper to therecording mechanism the rod 54 resumes its normal position, as shown in Fig. 1, and the springs 20 and 62 again engage the pawls 18'and 60, respectively, with the ratchet wheel 21, and also exert a backward pressure upon the actuating element 58 sufficient to restore said element and the lever 56 to idle position.

During certain operations of the machine it is desirable that the item counting or indicatin devices 3738, and the train of key 100 g, be prevented from operating.

ing through a hole in the case,

The two pawls are thus released from In order to prevent operation of the item counting or indicating device and the train of key locking devices it is only necessary to disable either the pawl 18 or the pawl '60, or some other part 0 the train of operatin connections. In the resent instance I have illustrated a device or disabling the pawl 60, by disengaging said pawl 60 from the ratchet wheel 21, so that when the actuating pawl 18 is reciprocated the ratchet wheel 21 will oscillate or rock with the pawl 18; inasmuch as forward movement of the pawl 18 actuates the ratchet wheel in one direction, and when the pawl 18 moves backwardly the spring 24 actuates the ratchet wheel in the other direction and causes said ratchet wheel to follow the pawl 18 in its oscillating movements. The device for effecting disengagement of the pawl 60 from the ratchet wheel 21 comprises a screw 63 operatively extendand having its inner end adjacent to a projection or arm on the pawl 60. A suitable handle or knob 64: on the outer end of the screw 63 constitutes means for manual engagement for the purpose of operating the screw 63 effectively to disengage the pawl 60 from the ratchet Wheel 21, all of which is obvious in the illustration of these elements in Fig. 2.

I have illustrated the present embodiment of my invention selectively settable at the will of the operator to lock thekeys against operation, automatically, after a predetertermined number of items have been listed or added, the locking mechanism being actuated or controlled by the main shaft of the machine. It is obvious, however, that the locking mechanism may be otherwise actuated, and it is only material or essential that the machine be disabled at predetermined periods. It is not material that the devices be of the specific form or arrangement, nor that they be actuated in the spe cific manner, shown and described, for various modifications and alterations will readilysuggest themselves to those skilled in the art to which the invention relates. I do not restrict myself to specific features, but
